Zinedine Zidane's 18-month tenure at Real Madrid has ushered a glorious chapter in the club's already glittering history, with the Frenchman guiding Los Blancos to back-to-back Champions League titles, a LaLiga crown and a Club World Cup for good measure. 

Real Madrid's unprecedented achievements in the European competition resulted in inevitable comparisons to Pep Guardiola's all-conquering Barcelona side of the 2008-09 season, when the Blaugrana scooped a treble, winning 42 of their 62 competitive games in the process. 

Accurately measuring greatness from one era to the next is an impossible and thankless task. There are too many variables to factor in and, simply put, there is no way of telling who would beat who. Nonetheless, Real Madrid's upsurge in form since Zidane's appointment has certainly put them in the greatest team of all time debate.
